"Green Flash" Traveling on the Japan ocean side, you'll have the chance to see the moment the sunset falls on the horizon on a sunny day. It is a moment when you are about to make a "juh!" sound, but you can see another rare phenomenon just before sunset. This Green Flash is a sight that I have tried many times over the years in Fukaura Town in Aomori Prefecture, but I am sure that it can be seen along the coast all over the country. Even if you live in an area far from the sea, this is a scenery that you should definitely see when this corona turmoil calms down.
